With everything perfect, no attachment air leaks, slide not hardly worn, pilot jet is .025 and adjusts perfectly, 380 main jet ( 12" mini mufflers, no fibreglass in them, pretty much straight through) .107 needle jet, needle 2nd from the top, 3 & 1/2 slide, 357 full race cam. Can anyone tell me why I can not get a 900 RPM tick over, like some of the carb 101 service sheets say I should get. The best I can get is a really nice tick over at 1000 RPM. When running a 357 cam is this the best a fella can expect from a 1962 Rocket Gold Star. Alloy head , single carb, large intakes 1.5 inch Intakes, standard exhaust valves, these are the low longer street pipes, not the siamese scrambler pipes.
The Amal people said this was delivered with with a 389/081 carb , 1 3/16's venturi, Pilot jet .30, 440 main jet, 107 needle jet, needle stamped D, #4 cutaway , needle 2nd from the top. This bike was factory delivered with high siamese exhaust straight thru no baffles or mufflers, is the RGS scrambler model according to Ian Jackson. BSAOC club president this chapter in the U K. He has the dispatch records for this bike's numbers. Just basically need to know if 1000 RPM is as low as I can expect to get with this cam and exhaust set up, and the carb jetting I mentioned.
THANKS IN ADVANCE
